Area Forecast Discussion
National Weather Service Cleveland OH
400 PM EDT Wed Sep 2 2026

.WHAT HAS CHANGED...
The threat of severe storms has trended up for Northwest Pennsylvania
with an Enhanced Risk (level 3 of 5) for Erie County PA. This
includes a threat of damaging winds and potential for a tornado.

&&

.KEY MESSAGES...
1) Several rounds of thunderstorms are possible through midday on
Friday. Thunderstorms may be strong to severe at times, including a
threat of heavy rain and flash flooding.

2) Hot and humid conditions are forecast to continue on
Thursday. Heat index values are forecast to be in the upper 90s
for another day in Northwest Ohio with upper 80s to lower 90s
forecast in Northeast Ohio.

3) Cooler and drier weather is expected for the holiday
weekend.

&&

.DISCUSSION...

KEY MESSAGE 1... A broad ridge remains in place across the Mid-
Mississippi and Ohio Valley Regions. Hot and unstable conditions
remain in place with dewpoints in the low 70s and ML CAPE values of
2500-3000 J/kg. Temperatures of 10C at 700mb can be a good indicator
of a capped environment and this threshold extends to just north of
Mansfield in the west but south of Youngstown in the east. So far a
lack of forcing has been a limiting factor for thunderstorms this
afternoon but that could change this evening.

The active storm track extends around the periphery of the ridge
from Iowa across Central Lower Michigan to New York. We are seeing
some cu trying to build across the snowbelt region with isolated to
scattered storms possible in this area between 4-8 PM. The first
couple showers that have developed have struggled to grow
vertically. We will have to see if this initial activity has
strong enough updrafts to be severe. Later this evening, the
shortwave crossing lower Michigan will move towards New York and
expect the potential for scattered strong to severe storms to
move south into Northwest Pennsylvania, likely extending
westward into Ohio. Effective shear values will increase to 40+
knots this evening coupled with backed flow in the low levels
downwind of Lake Erie. The SPC has raised the severe weather
outlook across New York and extending into Erie County PA to an
Enhanced Risk (level 3 of 5) while a Slight Risk (level 2 of 5)
remains from nearly Toledo to Youngstown. Main time frame for
organized severe storms looks to be in the 7 PM - 11 PM window,
then settling south across Northeast Ohio overnight. A few of
the CAMs show another push of stronger storms late tonight
moving southeast along the boundary but confidence is low in
that occurrence.

The overnight activity will set the stage for Thursday as the ridge
axis shifts slightly westward with northwest flow aloft. Instability
will be very high again and expect to see scattered showers and
thunderstorms develop with daytime heating during the afternoon.
This could initially be focused from northwest to southeast across
the eastern counties of Ohio but think we will see an expansion of
storms across much of northern Ohio during the evening. Still many
options for how this will evolve but the potential for severe
thunderstorms and heavy rain will continue. PW values of around
2 inches will support heavy rainfall. Good coverage of
thunderstorms are likely to persist Thursday night as a stronger
shortwave trough finally crosses northern Ohio. Showers with
scattered thunderstorms may linger into Friday but will become
focused across Northwest Ohio by Saturday as the overall
longwave pattern transitions to northwest flow with a trough
over New England.

KEY MESSAGE 2...

Temperatures will trend slightly cooler on Thursday as the boundary
settles south into the area. The hottest area will be along the I-75
corridor where highs will still be near 90 and heat index values
will reach the upper 90s. Given the potential for scattered showers
and thunderstorms along with partly cloudy skies, a Heat Advisory is
not planned for Thursday. This could change overnight if chances of
precipitation trend lower in the west or if more sun is expected.
Will see how the convection plays out first before deciding if
we need to an advisory for a few more counties.

KEY MESSAGE 3... High pressure will build south out of Canada on
Saturday and bring cooler and drier conditions through the Holiday
weekend. High temperatures will return to near normal values in the
upper 70s to near 80. Dewpoints in the upper 50s to low 60s will
bring lower humidity. A lower chance of precipitation will continue
along the I-75 corridor on Saturday with dry conditions in the
forecast Sunday through Tuesday.

&&

.AVIATION /18Z Wednesday THROUGH Monday/...
The airspace is starting with VFR conditions with some variable
cloudiness behind a round of storms in NE OH/NW PA this morning
and ahead of a developing line of storms in SE MI into Lower
Ontario. The line of storms to the northwest will fill in over
the next couple of hours as they move east-southeast across Lake
Erie into the airspace. The most likely impacts are going to be
at KERI, KYNG, and KCLE, although some convective activity could
reach KCAK, KMFD, and KTOL. Another line of convective activity
straddles further north across lower Michigan and will follow
east-southeast into the airspace later tonight, likely causing
some issues at similar terminals. There is lower confidence on
this round, as it will largely depend upon the first round
during the afternoon and evening hours.

There should be a reprieve in shower and storm activity during
the first part of the overnight hours, but additional shower and
storm activity is possible late tonight and again on Thursday.
Again, these are conditional on prior convective rounds. Any
thunderstorms over a terminal will have IFR potential.

Outlook... Non-VFR possible in shower and storm activity through
Thursday night.

&&

.MARINE...
The main marine concern over the next 36 hours will be several
rounds of showers and thunderstorms across the lake with the
potential for strong, damaging wind gusts and large hail. For
broader conditions outside of the storms, the lake is ahead of a
cold front this afternoon and will have southerly flow until the
cold front passes on Thursday evening. Some ridging will build
from the north for Friday and into the weekend and allow for
some elevated north to northeast flow. This flow could allow for
waves in the 2 to 3 ft range over the weekend, which would be a
problem for some moderate swimming risk for the western and
central basin beaches.
